Zero because when you divide the 2nd line by 3, you get x-5y=5, so they have the same slope and lines with the same slope are parallel. It's also easier to put it in slope-intercept form (y=mx+b) so here:
y= x(1/5) -2
y= x(1/5) -1
Answer:
y =(2/5)x - 1
Step-by-step explanation:
Slope intercept form: y = mx + b
m is slope and b is y-intercept
y =(2/5)x - 1
The last one as we can see that as the wight increases, the miles per gallon decreases.
